To all whom it may conw'm:

Be it known that we, .l'L'Lius D. Tstuorln and llntsox G. Gounau,citizens of the Unitcd States, residing at New Orleans, in the parish ofOrlea us and State of Louisiana have invented new and usefulimprovements in Flushing .Dwiccs, of which the following isspecification.

Our invention relates to flushing devices for water closets, and itsobject is to simplify and improve the construction of devices of thiskind.

In its preferable form the invention is embodied in the device set forthin the following description and accompanying drawings.

In the drawings: the ligurc shown is a centralvertical section of thedevice.

Referring to the drawings A is the body 01' the valve casingv it has aninlet opening B and an outlet pipe l C, the latter leading to the bowl.

Mounted on the pipe C is an operating lever D having an arm it mountedwithin the pipe and adapted to bear against a stem F to which is secureda pilot valve G. The pilot valve is held yieldingly on its seat by acoiled spring H surrounding the upper part or stud l of the valve stem.The upper end oi the coiled spring surrounds a dmvnwardly projectingstud .l which is provided with a. threaded head vli engaging screwthreads on the interior of a main flushing valve L. The screw stud Jserves as means to adjust the tension of spring ii.

The pilot-valve G is adapted to close and open port G which serves toestablish communication between the interior of the main valve and theoutlet pipe C.

The flushing valve is provided at its lower end with a rubber or leatherwasher M adapted to seat on the valve casing, and the valve is adaptedto control the communication between the inlet B and the outlet pipe C.Secured to the valve L is a skeleton cage N which moves in the pipe (land serves as a guide for the valve Land also to guide the valve stem F.

Clampcd in the upper end olihe valve L, by a threaded wash r O is aflexible diaphragm P, preforably ol' rubber. which is clamped aroundits'cdge to the casing by screws Q passing through the annular flange oian int-losing cap or cover B. An air and water chamber S is formed Lyand between this cap and the diaphragm. 'lhis chamber communicates withthe iutrja'ior of the valve L by holes or passage ways T iormcd in thscrew-stud J. In thecap It is a screw trap U for permitting ready accessto the chamber S. Depending from this trap is an adjustable stopscrew V,adapted to limit lheupw'ard movement of the diaphragm and which may beadjusted to regulate the extent of said movement.

The chamber S communicates with the inlet ll by a small pipe or passageway W, in which is mounted a regulating valve X, consisting of a screwextending against the beveled. seat Y in the pipe or passage way \l, theupper end of the pipe or passage way, Which is extended into the cap It,being provided with a closing screw Z.

The operation of the devi e is as follows: Upon raising the lever D andarm 1f, the valve stem F will be raised and the valve G raised from itsseat in the main valve L. Therenpon the water will be permitted toescape from within the main valve and from the chamber S into the outletpipe C. This escape of the water will relieve the pressure in thechamber S on th e diaphragm, and the latter will be raised by thepressure of the water from the inlet, carrying up with it the mainflushing valve L which thereby establishes communication between theinlet B and the outlet G and the water rushes into the bowl. At the sameline water from the inlet will pass in a comparatively small quantitythrough the passage way W into the chamber S. The flushing valve L willremain open and the flushing action be continued until the chamber S isfilled with the incoming air and water and the diaphragm forced out anddown so as to seat the valve L and close communication between the inletand outlet. The length of the flushing may be regulated by theadjustment of the screw X, which may be screwed down or up to lessen orincrease the size of the passage and thus regulate the flow of the waterpassing into the chamber and consequently the length of time of theflushing action.

The inlet B may be connected either to a tank or directly to a watermain.

It is clear that various changes in the details of the device may-bemade without departing from the principle of our invention.

Having thus described our invention, what we claim 1. The combination ofa substantially cylindrical casing, a discharge pipe lendingsubstantially centrally from the bottom of the casing, a main valve seatat the top of said discharge pipe, a hollow main valveresting; on saidseat, a diaphragm secured to the top of said main valve, 21 coversecuring the diaphragm to the using, a guide cage reciprocablc. withinthe discharge pipe and connected to the main valve for directing itsmovement, a pilot. valve seat within the main valve, a pilot valveresting on said seat and having; a stem passing through and to a pointbelow the guide cage, :1 spring resting upon the pilot valve, and anadjusting screw near the top of the hollow main valve forming anabutment for the spring and providing means of adjustment for the same.

2. The combination of a substantially cylindrical casing,

a discharge pipe leading suhstantialv centrally from the bottom of thecosine a main valve seat at the top of said ischarge pipe, a hollow mainvalve resting on said seat, a diaphragm secured to the top of said mainvalve. a cover securing the diaphragm to the casing", a guide cagereciprocable within the discharge pipe and connected to the main valvefor directing its movement, a pilot valve seat within the main valve, apilot valve resting on said seat and havin; a stem passing through andto a point below the guide 2 l p evaaav cage, a spring resting upon thepilot valve, an adjusting screw near'the top of the hollow main valveforming an abutment for the spring and constituting means of adjustmentfor the same, and a screw trap in the cover removable to permitadjustment of the spring.

3. Thecombination of a valve casing, a discharge pipe, an inlet pipe, ahollow main valve within the casing, a guide cage therefor movable inthe discharge pipe, a diaphragm connected to the main valve, anddividing the casing into an upper and a lower part, a by-paas leadingfromthe inlet to the upper part of the casing, a pilot valve within thehollow main valve, a spring holding the pilot valve normally on itsseat, a perforated screw memher in the main valve, serving as anabutment for the,

spring, as adjusting means therefor, and permitting fluid to pass fromthe upper part of 'the casing to the lnterion of the main valve, and astem on-the pilot valve extending through the guide and below the guidecage, and a finger actuated from outside the casing and adapted to raisethe stem ofthe pilot valve. 1

'4. The combination of a casing, a hollow main valve therein' and freefrom the-casing, a diaphragm connected to said valve and the casing, atubular member communieating with the casing, a guide cage movable insaid tubular member and connected to the main valve serving to guidesaid vgllve, an auxiliary valve within the main valve,

a spring forclosing the auxiliary valve, and a perforated abutmentcarried in the bore of the main valve serving to hold the spring againstthe auxiliary valve.

ti. The combination of a casing, a hollow main valve therein and freefrom the casing, a diaphragm connected to said valve and casing, atubular member communicating with the casing, a guide cage movable insaid tubular member and connected to the main valve serving to guidesaid valve, an auxiliary valve within the main valve, a spring forclosing said main valve, and an abutment for the spring adjustable inthe main valve for regulating the action of the spring. I

6. The combination of a casing, a tubular member communicating with thecasing, a main valve seat thereon, a hollow main valve within and freefrom the casing and seating on said main valve seat, a. guide cageconnected to the main valve and movable within the tubular member,

an auxiliary valve seat within the main valve, an auxlliary valveseating thereon, a spring tending to set the auxiliary valve, and anabutment adjustable within the main valve for regulating the pressure ofthe spring.

7: In devices of the character described, the combination, of a hollowmain valve, a valve seat therein, an auxiliary valve normally resting onthe seat, a spring urging the auxiliary valve to normal position, and anabutment for the spring adjustably mounted in the main valve.

In testimony whereof we have hereunto afiixed our signatures.
